These bad boys are hard to find these days (Vltor MUR Upper). I found it here at Alpha Ops and was hesitant at first since I had never heard of them before and there wasn't much on the internet about them. However I made my purchase, they shipped it the same day and 2 days later its at my door. Holy cow that was fast...excellent customer service. I haven't tested the fit on my Noveske Lower yet but I though I would go ahead and get a review up. The Vltor Upper is beautiful and the finish is amazing. All the surfaces are smooth and even and. This thing is a class above my JP Enterprises forged upper (which I was a little disappointed in). Especially because of its price. The JP upper was excellent, but I believe it was meant for a duty weapon so the finish wasn't the top priority. I want my AR to be a function no doubt, but it also needs to look damn good. So the Vltor upper was the obvious choice.
